Brimstone Quadracycle Custom Quads Deliver Performance

Every screaming-fast Brimstone Quadracycle bike is built to order. Custom seats, handle bars and foot peg locations are based on the buyer’s individual measurements: They really are machines fit for speed.

Combined with high-tech materials like carbon fiber, kevlar, titanium and magnesium, the Quadracycle’s lightweight construction is a daring pairing for a small block V-8 engine that delivers up to 750 horsepower through a four-speed automatic transmission.
